How to Repair a Gas Stove Burner

Professional chefs often prefer gas stoves because of the nearly-instant control they provide in the kitchen. In fact, gas burners take practically no time to heat up and their temperature can be adjusted much faster than when using an electric stove! On the other hand, they may come with a heftier price tag upfront, but a gas appliance will also save you money in the long run compared to the cost of an electric appliance. As undeniable as these benefits are, having a gas range in your home comes with a few considerations. For starters, servicing and maintaining gas stoves can be dangerous, especially when the proper steps aren’t taken to ensure safety. Fortunately, you can take steps to keep yourself safe, and your appliances in prime shape at the same time.

No matter how skilled you are with a toolbox, you should never attempt to repair a gas line on your own. Always turn off your gas supply before attempting to disassemble any components of your gas stove. Prevent gas leaks, exposure to toxins, and painful accidents by regularly maintaining your appliances by consulting Denver Appliance Pros. With that said, there are a few simple steps you can take to troubleshoot your malfunctioning gas burner.

Ignitor Won’t Spark

If you turn the burner knob on and see no spark, there are a few different potential causes for you to consider. For starters, you should be able to see a bright blue spark, which is what is used to ignite your burner. Therefore, if you can’t a see spark, then your issue is likely being caused by a faulty ignitor. If this is the case, first check to confirm that your unit is plugged in, that the circuit breaker connected to the unit is turned on, and that you aren’t dealing with a blown fuse.

Some problems are easy to diagnose yourself, but if you’re unsure of how to proceed, please don’t hesitate to contact a certified appliance professional.

Make Sure the Burner Cap is Not Misplaced

A common cause for a gas stove burner refusing to light is a lost or loose burner cap.

Your burner won’t ignite if the cap isn’t sitting in the proper position. Therefore, always check that each of your burner caps are aligned correctly before attempting to ignite the burner.

Problems With a Spark Module

Once again, if you’re having trouble with your burners, you might have a faulty spark module.

Consult our stove repair guide to ensure your ignition switch, electrode and spark wires are all working well.

If your range has power, the burner caps are aligned, but the spark is still weak, your spark module may have failed. You can usually tell your ignitor is failing because the spark will appear much fainter than usual.

In this case, a spark module replacement will fix the problem and get your burner back to full capacity in no time.

When you turn the knob on your stove, electricity flows to the ignitor, and gas flows to the burner.

Listen for a click when you turn the knob. If you hear a clicking sound but your burner won’t light, your ignitors might be failing.

Unfortunately, when an ignitor fails, there’s no other way to resolve the issue other than by replacing the entire component.

If it looks like you need an ignitor replacement, don’t hesitate to give us a call.

We will happily help you diagnose and repair whatever your unit needs.

Problem With Gas Supply

Ensure the Burner Is Not Clogged

The problems presented by your gas stove burners could come down to issues with the gas supply. With that said, any repairs to do with your unit’s gas supply lines should only be performed by a trained, licensed professional. Furthermore, if you suspect a gas leak, make sure to turn off your gas supply immediately, and contact your supply company. Aside from that, you’ll want to start by checking that your burner is not clogged.

As hard as we try to keep our kitchens clean, there are small holes in your range burner, which allow the gas to flow through. However, not all of us think to clean these regularly, which often leads to blockages and a reduced gas flow. To clean it, remove the burner grate and clean the area with rubbing alcohol or a damp, soapy cloth. Additionally, you can use a toothpick or sewing needle to clean away any small particles that are blocking the holes.

Replacing the Knob

The knobs on your stove can become damaged over time, once again causing an issue with the unit’s gas flow. To remove these knobs for cleaning, gently pull on the knob and it should simply slide simply off the shaft.

After cleaning, you might want to consider replacing the knobs, especially if you find they are not turning as easily or if the back of the knob appears to be worn out in any way.
